WATC H PEN DANT.

SPECIFICA'IION forming part of Letters Patent No. 450,579, dated April14, 1891,

Application filed October 27, 1890, Serial No. 369,475, (No model.)

To all whom it may concern:

Be it known thatI, FRANK G. FAXON, a citizen of the United States,residing at Mount Morris, in the county of Livingston and State of NewYork, have invented an Improvement in lVatch-Iendants, of which thefollowing is a specification.

The object of this invention is to reduce the weight of precious metalin the pendant and thereby lessen the cost of manufacture, and also tosecure the ends of the bow more reliably than in the safety-pendantswhich have heretofore been manufactured.

In some of the safety-pendants heretofore made peripheral grooves areformed in the metal of the bow near the ends thereof, leaving heads thatare received and grasped by notched shells that are secured within thependant.

By my present improvements the pendant is rendered very strong anddurable and the bow is reliably connected thereto, and the strain andwear come principally upon the interior portions of the pendant and butlittle on the shell of precious metal, and the parts can be separatedwith facility whenever necessary.

In the drawings, Figure l is a vertical section of the pendant and apartial elevation of the sleeve or tubular screwshanlt. Fig. 2 is aninverted plan, and Fig. 3 a section of the locking ring or bush. Fig. ais a plan, and Fig. 5 a section, of the lower bushing. Fig. 6 is asection of the tubular screw-shank in a modified form, and Fig. 7 is aninverted plan of the same.

The capsule or shell A of the pendant may be made in any desired manner,but it may be thinner than usual and of precious metal or plated. Thelower bushing E is in the form of a ring screw-threaded on the inside,and the exterior corresponds in shape to the interior of the shell orpendant A, and such bushing E may entirely or partially till the lowerpart of the shell A, and it is preferably made with a peripheral grooveE, as shown in Fig. 5, so that it will be firmly scoured into the shellof the pendant by swaging or rolling the metal of the shell into thisgroove, as seen in Fig. 1; but this bushing E may be soldered orotherwise firmly held into the pendant-shell, if desired.

The locking-ring or upper bush F is removably fitted into the shell A ofthe pendant, and the bow B of the pendant is made with parallel ornearly parallel ends peripherally grooved, as at 2, leaving heads at theextreme inner ends of the bow, and the cross hole that is bored into thependant for the reception of the ends of the bow is partly in the uppersurface of the bushing E and the lower surface of the locking ring orbush F; but a portion of such hole in the locking ring or bush F isformed with semicircular ribs 3 to fit the peripheral grooves 2 in thehow 13, and the semicircular recess in the top of the lower bushing E isplain, in order that the ends of the bow B may be introduced freely intothe pendant and brought to position, after which the locking ring orbush F is introduced into the shell of the pendant.

The sleeve or tubular screw-shank D is formed with a head that setswithin the shell A upon the locking-bush F, and such screwshank passesthrough the locking-ring F, and screws into the lower bushing E, therebyfirmly holding the locking ring or bush F in position and clamping theends of the bow 13, but allowing such bow to be swung, as usual. The topsurface of the bushingE and the bottom of the locking-bush F should be aslight distance apart to allow for screwing up the shank D from time totime to compensate wear or looseness in the ends of the bow, and thehead of this screw-shank is notched for the reception of a screwdriver.

The crown G is of any desired character. Usually it is recessed for theupper end of the pendant, and the spindle H, which passes through thescrew-shank D, is connected with this crown G, so as to be rotatedthereby, and this connection may be made in any usual manner.

In Fig. l the spindle II is represented with an enlargement adjacent tothe inner end of the screw-shank D, to prevent the spindle being drawnout, thus adapting the present improvements to watches containing apush- IOO When this improvement is used with a crown winding and settingmechanism, in which the crown is moved to draw out the spindle H or topush it in for winding or setting, then the tubular screw-shank D ispreferably prolonged in the form of a thin split tube 6, as shown inFigs. 6 and 7, with an in wardly-projecting inclined flange, so that thespring-tube will hold thespindle H in its normal position for winding,or allow such spindle to be drawn outwardly to connect the same with thehand-setting mechanism. I provide a small hole at 8 in the crown, whichhole is in line with the cross incisions in the head of the tubularscrew-shank, so that a pin inserted into this hole 8 will pass into oneof such incisions and connect the crown and the tubular screw-shank, sothat the latter may be rotated to tighten the parts up, as may becomenecessary. By unscrewing the tubular shank the winding stem or spindlecan be withdrawn to allow the movement to be taken out of the case,thereby doing away with the separate fastening-screw that is usuallyprovided.

I claim as my invention 1. The combination, with the shell A, of abushing fitting the interior of the pendant and permanently secured tothe same, said bushing having a central screw-threaded hole, the bowhaving peripheral grooves near its ends within the pendant, thelocking-ring within the shell of the pendant and having ribs to fit thegrooves in the bow, and atubularscrew-shank passing through thelockingring and screwing into the bush to connect the parts together andsecure the ends of the 1 how, substantially as set forth.

2. The pendant-shell, and the bushing received within the same andpermanently secured thereto, in combination with the how, the ends ofwhich pass through the shell and into recesses in the upper surface ofthe bushing, the locking-ring within the shell and having projectionsthat engage recesses or grooves in the bow, a tubular screw-shankpassing through the locking-ring and screwing into the bushing andhaving a head pressing upon and securing the locking-ring, such headbeing slotted, the crown, and the spindle to which the crown is secured,and which spindle passes through the tubular screwshank, there being ahole in the crown for the insertion of a pin through the slot of thescrew-head, substantially as set forth.

3. The shell or pendant and the bushing within the same permanentlysecured thereto and having a central screw-threaded hole, in combinationwith a locking-ring Within the shell for securing the ends of the how, atubular screw-threaded shank provided with a head for holding thelocking-ring in position,

and a thin tubular extension slotted to form springs, and a spindlewithin the screw-shank and the crown connected with such spindle andadapted to move the same endwise, substantially as set forth.

Signed by me this 22d day of October, 1890.
